Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492526, here are decompositions:

73 + 31492453 = 31492526
97 + 31492429 = 31492526
103 + 31492423 = 31492526
127 + 31492399 = 31492526
157 + 31492369 = 31492526
283 + 31492243 = 31492526
313 + 31492213 = 31492526
433 + 31492093 = 31492526

Showing the first eight; more decompositions exist.
